A former soldier from New Zealand, Duncan Sandilands, has teamed up with a Brisbane-based barrister Mark Plunkett to launch a campaign to close a loophole in Australia’s immigration legislation which seems to bar citizens of New Zealand from joining the Australian Defence Force.

The woman at the centre of the “stupid, fat Australian” case has won an appeal against her 2012 conviction after a north-west England court determined that it would not be in the public interest to uphold the court’s original verdict.

New Zealand Prime Minister John Key has raised questions over the treatment of New Zealanders in Australia, claiming that the current Australian immigration system unfairly prevents long-term Australian residents from applying for citizenship and obtaining the right to vote or claim government benefits.
